A push-up bra on its own is a great cleavage enhancer, but pair that with the plunge cut and you’ll achieve the strongest natural cleavage while being able to wear it with virtually anything! The push-up has padding at the bottom or sides of the cups, which literally pushes up the bust, while the plunge cut will push the breasts together and upwards. Most plunge bras have a little push-up padding, and the cups sit very low in the center for a super deep-v neckline. This type of bra is ideal for low cut tops that would show the top of a regular bra.
